Nine-figure flex: spot Bitcoin ETFs bank $998.95M in a day, send average holder back to the green

U.S. spot Bitcoin ETFs pulled in a net $998.95 million on Monday, the largest single-day haul since bitcoin reached a record high of roughly $126,200 on Oct. 6, 2025, according to SoSoValue. Bloomberg Intelligence analyst Eric Balchunas characterized the figure as the biggest one-day total since last October, while data from CoinDesk and SoSoValue ranked it the ninth-largest inflow since the funds began trading on Jan. 11, 2024. Bitcoin ($BTC) climbed to around $85,882.16 on Monday, with prices briefly trading near $85,900, about 5% above the estimated average cost basis of $81,722 a coin for U.S. spot Bitcoin fund holders, according to Balchunas' colleague James Seyffart. That move pushed the average buyer of a U.S. spot Bitcoin ETF back into profit for the first time since January.

BlackRock's IBIT led the day with $381.37 million in inflows, followed by Ark & 21Shares' ARKB at $289.12 million and Fidelity's FBTC at $238.84 million. Morgan Stanley's MSBT added $61.67 million and Bitwise's BITB $21.56 million, while Grayscale's two funds each took in single-digit millions and VanEck's HODL and Valkyrie's BRRR posted zero flows. The session marked the first three-day streak of gains in two weeks, according to CoinDesk, and came days after bitcoin absorbed a failed Senate cloture vote on the Clarity Act and a Federal Reserve interest-rate increase.

"With the average buyer finally in the green, whether institutions want more Bitcoin exposure or were riding the last rally should now be clearer," said David Wachsman, president of Hawkeye Digital. He added that holders sitting on losses "often sell the first chance they get to break even," meaning much of this year's demand has had to absorb that supply. "Bitcoin's recent recovery toward the $86K–$87K range is being supported by renewed institutional demand, stronger spot ETF inflows and evolving US regulatory developments," said Vikas Gupta, country manager for India at Bybit, noting the market has held up despite the Fed's rate hike and the failure of the Clarity Act.

The funds turned over about $4.5 billion on Monday, which Seyffart called not especially high given the size of the move in bitcoin and slightly below the $4.6 billion they traded on Friday. Balchunas said the figure was elevated compared with stock and gold ETFs and that IBIT was at or near the top 10 by volume. He cautioned, however, that flows assigned to a session largely reflect the previous one, meaning Monday's total probably captures Friday's buying rather than Monday's, and the response to Monday's move remains to be seen.

Cumulative net inflows since launch now stand at $56.16 billion, with the funds holding $110.14 billion, equal to 6.30% of bitcoin's market capitalization. The monthly tally has climbed to $1.31 billion, following August's $3.52 billion in inflows, and bitcoin has risen 44% to roughly $85,000 this quarter, outperforming every major asset including gold. Spot ETFs remain down $450 million on a year-to-date basis.
